EOS 3 AF points

I'm wondering if anyone else has this problem and/or knows of a fix... I did a quick search but nothing turned up

The AF points on my EOS 3 are slightly tilted (maybe 3-5 degrees) and skewed (about a half to one AF box downwards) so they don't like up properly with the ellipse in the viewfinder. Presumably the light that projects the points onto the focusing screen has moved slightly?
